VALVE-GAP FOR HIGii-PIRESSUR'E WELLS.

Application filed May 28, 1920.

1 'o (1/ l whom 1' t may concern Be it known that l Rsuunrr Iii. l nimnien a citizen of the l uitwl h'tulce oi' Anusi'im, residing at Duquesne. in the county of Allegheny and State of lcnnsylvunin, have invented new and useful Improvements; in Valve-(zips for I-ligh-Pressure ii'clls. of which the following is a specification.

The object of the invention is to provii'lc a relatively simple and villi-ionic means to:- capping and controlling the discharge from high pressure or spouting oil and wells; as distinguished from those in which material must be removed by a. pumpn process, the construction of the apping means being such to facilitate its npplt cation to the oil well tubing either prior to or during the discharge of the product there from, and to facilitate the control of the flow of "as or oil after the cop )ing opera tion has heen effected; and with objects in view the invention consists in a construe I tion and a combination of parts of which :2

preferred embodiment is shown in the an companying drawings wherein: H 7

Figure l is :1 side view of the capping device applied in the operative position to a Well tubing.

File. 2 is a similar View shoeing [ht step in applying the on with the n member thereof in its {lisplnvmi "cloths! lo the securing member.

Fig. 3 is it sectional view oi t.l'uzih'imshowing the parts in the positions whirl they occupy just prior to the adjust. rent of the valved, member to secure a tight between the lower extremity thereof and .i. terminal of the well tubing. v

Fig. 4 is a sectional view showing the parts in their operative relations with the valve open.

Figs. 5 and 6 are opposite side views at right angles respectively to the plane of Fig. 1 to show the link and latch respec tively in side elevation.

Fig. 7 is a transverse sectional view on the plane indicated by the line 7 7 of Fig. 1.

The cap consists essentially of a valved body member 10 having lateral outlets l1 communicating with coupling sleeves V2 for engagement by the adjacent extents of pipes for conveying the oil or gee to points of storage or use, the intermediary portion of the bore of the body member being reduced to form a valve seat 13 in. operative relation .with which is arranged a valve M actueble Specification of Letters Patent.

At the opposite side of the structure from the loose or swinging; link :21, which permits the movement of the body memberof the cop relative to the fastening or anchoring member formed by the clamping band in the operation of applying the device to the Well tubing. there is located a yielding latch 28 consisting of a spring tongue secured at its upper end to the ring 24 and shouldered at its lower extremity as indicated at 29 for engagement with a. seat 30 formed in a catch 81. permanently secured to the exterior sun fine of the Wall of the bend 17.

In the application of the device to the well tubing the arts being substantially in the position indicated in Fig. 2, the band 17 is placed around the tubing and adjusted by means of the bolt l9 to engage the some firmly after which the body member of the co is swung upward into alinemcnt with sis the tubing to occupy the position indicated in Fig. 3 and.,the latch 28 is snapped into engagement with the catch 31, after which the tubular body member of the cap may be screwed downward throu h the ring 24 to place the link21 and late 28 under tension and secure a firm and fluid tight joint between the lower end of the body member and the upper extremity of the well tubing. The adjustment of the valve 14 will then provide for the control of the discharge from the well as may be desired by the operator.

Obviously the removal of the cap from the well may be as readil effected by a reversal of the steps herein a ove specified, and the cap is therefore applicable successively to a plurality of wells as the output therefrom may require, no material modification in the construction of either the tubing or the cap being necessary in conneetionwith such successive applications.

What is claimed is:

1. A cap ing device for high pressure well tubing iaving a body member provided with a valved outlet, an anchoring or fastenin member for engagement with the well tu ing, and flexible connections between said members to permit of the swinging movement of the former with relation to the latter.

2. A capping device for high pressure oil. well tubing having a body member provided with a valved outlet, an anchoring or fastening member consisting of an adjustable clamping band for engagement with the well. tubing adjacent to its upper end, a link connecting said body member and band to permit of swinging movement of the former relative to the latter, and means for holding said members in alined relations. y

3. A capping device for high pressure oil well tubin having a body member provided with a va ved outlet, an anchoring member for engagement with the well tubing, and

provided with a valved outlet, an anchor band for engagement with the well tubing, and a ring movably connected with said anchoring member and adapted for registration with the tubing engaged by the latter, the tubular body member being threaded in said ring.

5. A capping device for high pressure oil well tubing having a tubular body member provided with a valved outlet, an anchoring member consisting of a contractible clamping band for engaging the well tubing, a ring having a link connection with said anchoring member and a latch for securing the ring in axial alinement with the anchoring member. the body member being threaded in said ring for terminal contact with the extremity of the well tubing.

6. A capping device for high pressure oil well tubing having a tubular body member provided with a valved outlct, an anchor ing member consisting of a contractible clamping band for engagingthe well tubing, a ring having a link connection with said anchoring member and a latch for se curing the ring in axial alinemeut with the anchoring member, the body member being threaded in said ring for terminal contact with the extremity of the well tubing and rovided with an exterior sleeve for embracing the upper extremity of said tubing.

7. A capping device for high pressure oil well tubing having a tubular body member provided with a valvod outlet, an anchoring member consisting of a contrnctiblc clamp for engagement with the well tubing, :1 ring loosely connected with the an horing mem-- her by an interposed link, and a latch membcr carri d by the ring for engagement with a catch on the anchoring member to retain the ring in axial alinement with the anchoring member, the body member being threaded in said ring for axial adjustment relative thereto and provided at its lower end with a sleeve for embracing the upper end of the well tubing, said sleeve having an internal shoulder for hearing contact with the extremity of the tubing.

In testimony whereof. I affix my signature. 100
